  Log Message:
  -----------
  [lld-macho] Extend PIE option handling

* Enable PIE by default if targeting 10.6 or above on x86-64. (The
  manpage says 10.7, but that actually applies only to i386, and in
  general varies based on the target platform. I didn't update the
  manpage because listing all the different behaviors would make for a
  pretty long description.)
* Add support for `-no_pie`
* Remove `HelpHidden` from `-pie`
